For almost 10 years, while maintaining a stable quality, I liked specification .... not the ink on the ruler, and love this series on public and private both.
Pen of ink that has been used in the company will be broken suddenly, we reluctantly use something of the company distribution of "Tomorrow delivery" companies, but it does not much change in the specific price. In addition, because much cheaper than the nearby hardware store, to purchase in accordance with the time to order other goods, so as not Kirasa the preliminary.
Once, there was a thing that I bought a replacement ink, and think about the time of the exchange bottle and labor management, I think as cheaply as those who have purchased the pen body is a result.

Highlighter pen in the company of consumables (large order goods) will be paid, but the ease of use that the ruler is not dirty, other products you have when you defile the article larger amount out ink if not used for a while but, since this product is also a safe material for there is no it, we dare to buy at private expense.
Because cheaper than the hardware store, Once became no longer likely, it has been supplemented as appropriate.
